The method includes: obtaining 3D human body model data, and classifying the 3D human body model data into multiple data sets according to a predetermined classification condition, wherein the predetermined classification condition includes medical anatomy category information and art resource category information; determining, according to each of the data sets, a duplicate resource in the data set, and reorganized data sets where the duplicate resource is removed; and packing each of the duplicate resource and the reorganized data sets into a respective data package, and storing all of the data packages.

An image display method includes: obtaining a homography matrix between a first target plane and a second target plane according to the first target plane and the second target plane; obtaining a target displacement according to the homography matrix and an attitude; obtaining a target pose according to the target displacement, the target pose including a position and an attitude of a camera coordinate system of a current frame image in a world coordinate system; and displaying an AR image according to the target pose.

A student terminal is for viewing a class given in a virtual space that is immersive. The student terminal includes: a VR function section configured to display the virtual space according to virtual space information; and an input section for receiving a video capturing a desk of a student who views the class. The VR function section extracts, from the video, an area including a top plate of the desk corresponding to a desk object in the virtual space, and performs image composition for fitting a video capturing the area onto a top plate of the desk object.

This application provides a method and an apparatus for interaction processing of a virtual item, an electronic device, and a computer-readable storage medium. The method includes displaying at least one idle virtual item in a virtual scene; moving a first virtual object in the virtual scene in response to a movement operation on the first virtual object; displaying a pickable prompt of the idle virtual item when there is no obstacle between the idle virtual item and the first virtual object; and controlling the first virtual object to pick up the idle virtual item in response to a picking-up operation by the first virtual object.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for multi-layer reprojection techniques for augmented reality. A display processor may obtain a layer of graphics data including a plurality of virtual objects. Each the plurality of virtual objects may be associated with at least one bounding box of a plurality of bounding boxes. The display processor may further obtain metadata indicative of at least one edge of the at least one bounding box of the plurality of bounding boxes, and metadata corresponding to reprojection instructions associated with each of the plurality of bounding boxes. The display processor may reproject the plurality of virtual objects based on the metadata indicative of the at least one edge of the at least one bounding box and the metadata corresponding to the reprojection instructions.

Exemplary methods and systems that provide a curved path trajectory that can be used with a bendable medical device. The curved pathway can comprise straight and curved concatenated arc segments. The methods and systems can provide planning, visualizing and treatment of, for example, temporal lobe epilepsy (TLE) using laser interstitial thermal therapy (LITT) or tumors using ablation therapy. With curved pathway, the physician can create plan for intervention to avoid critical structure and to cover more target volume for treatment/diagnosis than straight pathway

There is provided an information processing apparatus and method capable of more easily comparing 3D objects. Comparison information which is information for displaying a plurality of 3D objects of 6DoF content in a comparable manner is generated. Further, the plurality of 3D objects of the 6DoF content is displayed in a comparable manner on the basis of comparison information which is information for displaying the plurality of 3D objects in a comparable manner. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, an information processing system, and the like.

A brain stimulation simulation system and method according to a preset guide system using an anonymized data-based external server are provided. According to various embodiments of the present invention, provided is a brain stimulation simulation method according to a preset guide system using an external server, the method performed by a computing device, the method including: a first server generating a global matrix for performing brain stimulation simulation on a plurality of objects by using a plurality of brain models for each of the plurality of objects; and a second server being provided with the generated global matrix from the first server and performing the brain stimulation simulation on the plurality of objects by using the provided global matrix.

A 3D calling system can provide 3D calls in various modes according to transitions and can provide affordances (i.e., visual or auditory cues) to improve 3D call image capturing. The 3D calling system of a recipient in a 3D call can display a hologram (from images captured by an external capture device (ECD)) or avatar of a sending call participant in a variety of ways, such as by making them “world-locked,” “ECD-locked,” or “body-locked.” The selection of a 3D call mode can be based on factors such as whether an ECD is active, whether the ECD is in motion, and user selections. In various cases, the 3D calling system can trigger various affordances to improve the quality of the images captured by the sender’s ECD, such as a displayed virtual object and/or an auditory cue, either signaling to the user that a current ECD configuration is non-optimal and/or providing instructions for an improved ECD configuration.
